Yesterday, I got 95 points in the math tutoring exam. I made a mistake in filling in the blanks and writing questions. The teacher reviewed the fill-in-the-blank questions for us before the exam. I didn't recite it carefully, but I remembered it carefully. I was thinking about something else when I recited it, and I didn't remember it at all. So when I took the exam, I couldn't remember it anyway, so I just filled in the numbers. I didn't see the meaning of the title clearly, so it was wrong to write "X" as "+". This grade, the first 1 question is because my attitude is not correct, and the second question is because I didn't review it carefully. I will definitely do these two things in the future, but I can't be careless. Teacher, I can't get satisfactory results in every exam. Since I took interesting math, I understand that the most important thing in learning math is understanding. It's no use just copying other people's answers. It's no use copying them. So I will listen carefully in the future and strive for excellent results.
It will be cloudy on Wednesday, March 23rd.
Today, after I signed up for school and went home, I wrapped the book cover and began to calculate the cost of this semester.
The first is tuition. Tuition fee is 4 10 yuan, plus drinking water fee in 20 yuan, 430 yuan. Next, the charge of the Olympic Mathematics School is 180 yuan. It is estimated that the bus fare is in 20 yuan and ***200 yuan. There is also money to buy exercise books: 2 copies of "Classpass" 2 1.5 yuan; English practice 1 9.9 yuan; 2 copies of Examination Paper Course Pass 15.9 yuan; "Jiangsu Big Test Paper" 3 copies 2 1 yuan. 21.5+9.9+15.9+13+21= 81.3 (yuan).
Study fee: 430+200+81.3 = 711.3 (Yuan).
Living expenses: I will drink about 5 cases of milk this semester, 5×30= 150 yuan. Every meal is about 2~3 yuan, of which 2.5 yuan is 2.5×3×30×5= 1 125 (yuan). "What else?" I bit my pencil and said to myself, "and your school supplies." Hey, mom's home. Yes, and school supplies.
School supplies: a pencil-box 8 yuan, a pencil-box 3 yuan (very cheap, clearance goods), six pencils 3 yuan, an eraser 0.5 yuan, two triangular rulers 1 yuan, two mechanical pencil 5 yuan, 8+3+0.5+ 1+5=20.5 (yuan).
Total expenditure: 711.3+150+1125+20.5 = 2006.8 (yuan).
Wow, I didn't expect that I, who usually don't spend much money, would let my parents spend 2006.8 yuan this semester. It seems that I will save money!

Our new math teacher.
One golden September, the new semester began, and I was lucky to meet a new math teacher-Zheng Yang. When you hear this name, don't think it's a man. In fact, she is a female teacher. Tall, with big eyes, he looks like a middle school student. The first lesson she gave was: multiplication and division. She not only drew pictures when analyzing math problems, but also quoted examples from life over and over again until we fully understood and nodded to her. Teacher Yang taught me so well that the first class left me with endless memories.

Why do we like chatting in class?
Yesterday, Teacher Yang asked us to discuss why some students like to chat in class. I don't think the reason for this kind of thing is unique. I remember one time when I was a foreign teacher, a classmate sitting next to me didn't like English class and couldn't understand what the American teacher said. So he talked to me secretly. I "discussed" with him because I couldn't stand the temptation of his Disney topic. Later, it was criticized by the teacher. I think: Talking in class will not only affect your own study, but also affect others' study. We must get rid of these bad habits.

Weigh shoes
There is a problem in today's math homework to weigh a pair of shoes. So I went to my mother and asked for a scale. Mom said she didn't have weighing scale. What shall we do? However, as the saying goes, "Nothing is difficult in the world". I think there must be a way.
So, I used my clever brain and came up with a homemade balance.
I cut off the paper covers of the empty moon cake box piece by piece, put on transparent tape, folded one of the paper covers into a regular triangle and put it on the table. Another piece of paper is made into the left and right disks of the balance and placed on the triangle in a balanced way. Then find something with weight at home as a weight. For example, my mother bought toothpaste, lipstick and other items, including 120g, 40g, 18g, 3g.
I'm very excited to say that the shoe activity has started. I put the shoes on the left side of the homemade balance and the "weight of goods" on the right side. It is best to balance the weight on both sides. Then the sum of the weights is the weight of my shoes. Exactly 86 grams. Hard work pays off! I finally finished my math homework. Mom praised me when she found out. Also jokingly said to me: "In ancient times, there was a clever Cao Chong as an elephant, and in modern times, there is a clever Hung Hung as a shoe!" " "Say that finish, everyone laughed.
It turns out that there are scales everywhere in life!

Happy math class
In yesterday's math class, Teacher Yang told us about "going to the playground". Because this is an interesting project, the students are very active in asking questions. I am no exception. After thinking about it, I raised my hand and asked such a question: "Is 200 yuan enough for 16 people to finish three projects?" Teacher Yang praised me for asking a particularly difficult question. However, at the prompt of Teacher Yang, I also helped my classmates to answer the questions. I remember a scientist said, "It is often more difficult to ask a question than to solve it." In this math class, we not only raised many questions, but also solved many problems. How amazing we are!

I'm great.
Today, we go to Happy Valley to play. The adult entrance ticket price of Happy Valley is: 140 yuan; Half a ticket for children. While waiting in line to buy tickets, my mother asked me to calculate how many tickets we need to buy. I blurted out, "I want 700 yuan." My mother asked me in surprise how I calculated so fast. Actually, I think so: four half-price tickets for children are equal to two adult tickets, plus three adult tickets are exactly five adult tickets, and five tickets for 140 are exactly equal to 700 yuan. Mom praised me for being great!

How many times does Shenzhou VI circle the earth every day?
Today, when the director of Beijing Aerospace Control Center told the reporter interviewed, "It takes 90 minutes for Shenzhou VI to orbit the earth once." After listening to it, I thought, "So how many times can Shenzhou VI circle the earth in one day? So I quickly calculated with my brain: there are 24 hours in a day, 1 hour is 60 minutes, that is, 24 times 60 is a day 1440 minutes. Then divide 1440 minutes by 90, which is equal to 16 laps. Also, Shenzhou VI will explore in space for five days, that is, 80 times around the earth. Astronauts are really amazing!

Count soybeans
Today's math class is a practical activity. We were divided into groups of eight people. Then the members of each group work together to figure out how many soybeans there are in 1 kg. According to the estimation method introduced in the book, it seems not difficult, but it is necessary to be careful to minimize the error.
I originally suggested that our group would use more cups accurately. But I can't find the cup. Later, this group of people chose the method of grasping by hand. Team member Luo Guangyuan is responsible for catching. Oh, dear! Luo Guangyuan's little hands are quite big! One catch is 180 grains, and 30 consecutive catches have just finished 1 kg of soybeans. Finally finished. 30 180 equals 5400 capsules. So I know there are about 5400 1 thousand soybeans.
This practical activity inspired me. I might as well try melon seeds, candy and peanuts. In fact, math problems are closely related to life.
